A client with pneumonia is receiving antibiotic therapy. Which finding indicates that the treatment is effective?

Correct Answer: C

Rationale: The correct answer is C: Increased breath sounds. When a client with pneumonia is receiving antibiotic therapy, increased breath sounds indicate that the lungs are clearing and the pneumonia is resolving. This improvement in breath sounds suggests that the antibiotics are effectively treating the infection. Choices A, B, and D are incorrect because a decreased white blood cell count, decreased respiratory rate, and increased heart rate are not specific indicators of the effectiveness of antibiotic therapy in treating pneumonia. While these parameters may change in response to treatment, they do not directly reflect the resolution of the pneumonia infection.

Correct Answer: D

Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.

Correct Answer: B

Rationale: Reassessing the client's blood pressure using a larger cuff is the most important action for the nurse to implement in this situation. Using the correct cuff size is crucial for obtaining accurate blood pressure readings. By reassessing with a larger cuff, the nurse can ensure an accurate measurement and proper monitoring of the client's blood pressure. Choice A is not the best option as it doesn't address the immediate need for accurate blood pressure measurement. Choice C is not the most appropriate action at this time since the immediate concern is ensuring correct blood pressure assessment. Choice D, while important, is not the most critical step in this scenario where immediate reassessment is needed with the correct cuff size.

Correct Answer: A

Rationale: The correct first action for the nurse to take is to check the IV tubing for obstruction. This step is crucial in ensuring that the IV fluids are flowing properly and that there are no blockages preventing the correct infusion rate. Increasing the flow rate (Choice B) without confirming the tubing's status could lead to potential complications if there is indeed an obstruction. Changing the IV site (Choice C) is not the priority in this situation unless there are specific clinical indications. Notifying the physician (Choice D) can be done after checking the tubing for obstruction, as the physician may need to be informed depending on the findings.

Correct Answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

Correct Answer: B

Rationale: In this scenario, the nurse should choose option B, which is to document the client's condition and communication with the surgeon. By documenting the client's condition and the communication with the surgeon, the nurse ensures legal protection and maintains continuity of care. This documentation serves as evidence of the actions taken, communication exchanged, and the rationale behind decisions made. Option A, notifying the nursing manager, may not be necessary at this stage unless there are specific institutional protocols requiring it. Administering additional fluids without further clarification may not be appropriate and could worsen the client's condition if not indicated. Calling the surgeon back immediately (option D) may disrupt the agreed-upon plan of action and fail to follow the surgeon's instructions of reassessment after an hour.

Correct Answer: B

Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.

Correct Answer: A

Rationale: The initial action the nurse should take after discovering a client's eviscerated wound is to cover the incision with a moist sterile dressing. This step is crucial to protect the exposed tissue, prevent infection, and create a conducive environment for healing. While notifying the surgeon is important, addressing the wound immediately takes precedence. Assessing vital signs is essential but should follow the immediate intervention of covering the wound. Placing the client in a supine position with knees bent is not the priority in managing an eviscerated wound; the first step is to cover the wound to protect the exposed tissue.

Correct Answer: A

Rationale: The correct approach for the nurse is to ask the client to elaborate on how their friends discourage them. By doing so, the nurse shows empathy, encourages the client to express their feelings, and gains insight into the situation. This open-ended question can help the nurse understand the specific issues the client is facing and work towards finding solutions collaboratively. Choices B, C, and D do not effectively address the client's concerns or encourage further discussion. Choice B is directive and may come off as judgmental, choice C assumes the friends are not supportive without exploring further, and choice D dismisses the client's feelings and the impact of peer influence.
